allowedOAuthFlows
The allowed OAuth flows.
code
Use a code grant flow, which provides an authorization code as the response. This code can be exchanged for access tokens with the /oauth2/token
endpoint.
implicit
Issue the access token (and, optionally, ID token, based on scopes) directly to your user.
client_credentials
Issue the access token from the /oauth2/token
endpoint directly to a non-person user using a combination of the client ID and client secret.
